To (ZZZ whom it may concern.

Be it known that I, HILAIRE on GHARDON- NET, a citizen of the Republicof France, residing at 22 Place Malesherbes, Paris, France, haveinvented new and useful Improvements in Apparatus for TreatingArtificial-Silk and like Threads, of which the following is aspecification.

My invention relates to apparatus for treating threadsof collodion orlike filaments with reagents or other suitable liquids, in order todenitrate, bleach, dye, or otherwise affect such threads under the bestconditions of uniformity and regularity. The particular object of myinvention is a bobbin so constructed as to carry the mass of threadintended to be subjected to the action of the reagents in a manner thatwill allow of the reagents circulating through the mass under the actionof centrifugal force when the bobbins are rotated in compartmentscontaining the liquid reagents. The present application is a division ofa copending application, Serial N 0. 40,272.

My invention consists in the construction, combination and arrangementof parts herein described and claimed, and illustrated in theaccompanying drawings, in which similar reference characters illustratecorresponding parts in all figures, and in which Figure l is alongitudinal section through the axis of a bobbin the component parts ofwhich are adjusted ready for winding on thread from the twistingmachine;

Fig. 2 is across section taken through the middle of Fig. 1;

Fig. 3 is a front elevation showing a bobbin at the end of the windingoperation and filled with thread; and,

Fig. 4 shows a bobbin in elevation after treatment mounted on astationary vertical spindle of the table of the winding machine readyfor the thread to be unwound.

Referring to the drawings, which illustrate a preferred embodiment of myinven-.

tion, the bobbin comprises a core or body A provided with a centrallongitudinal hole a. which has preferably two sets of radial rods, eachset being arranged in a single transverse plane, and the rodsterminating in points 6 7), of which one set I) are curved, and theother set I) are straight. These radial rods serve to hold the mass oftwisted thleild on the bobbin during the treatment The radiating rods 1)have their points curved as shown in Fig. 2 to facilitate the subsequentremoval of the thread, and are made of any suitable material which willremain unaffected by the reagent used for treating the thread, such aswood, ebonite, glass or enameled metal. These points are preferablysharp and have a smooth surface so that the thread will not catch uponthem when it is being unwound, and the length of the rods is such thatthe curved points project slightly beyond the mass of thread when thebobbin is fully wound, the maximum diameter of the thread beingindicated by the dotted line in Fig. 1 designated by the character (1.

The radial rods having the curved points 6 may be permanently fixed inthe core A; this set of rods is placed at the end of the bobbin whichwill be the top during the unwinding operation. The set of rods havingthe straight points 6', and which are. located near that end of thebobbin which is at the bottom during the unwinding opera tion comprisesindividual rods inserted in holes in the core, and held there merely byfriction, so that these can be removed when it is desired to unwind thethread from the bobbin.

Extending longitudinally of the core A and parallel thereto somedistance from the core are a number of rods 7", made of any suitablematerial. These may be rigidly secured to the core A and are long enoughto extend farther than the thread when the bobbin is fully wound (seeFigs. 3 and 4). These rods may correspond in number to the number ofrods in each radial set, and are preferably located immediately adjacentto theradial rods, as is indicated in Fig. 2.

Disks E are screwed or otherwise attached upon the axle B, and thesedisks have grooves 9 adapted to receive the ends of the core A. Inaddition, the disks E are provided with holes or depressions h which areadapted to receive longitudinal bars F which are made of wood or othersuitable material adapted to form a cylindrical surface at a distancefrom the core A slightly greater than the distance irom the core A tothe rods f so that the bobbin is adapted to be rotated by frictionalcontact with the drum D of the winding machine (see Fig. 8). This drum Dis provided with grooves opposite the sets of radial rods so as to allowof the remaining surface of 'the drum D contacting with the surface ofthe bobbin on which the thread is to be wound.

The operation is as follows: When the bobbin has been assembled asdescribed, it is taken to the winding machine, and the ends of the axleB placed in the bearings C of this machine. The frictional drum D isthen in contact with the rods or bars li and rotation of the drum D thuscauses the bobbin to revolve, and the thread is wound upon it.

Vv hen a bobbin has been completely filled" with thread, one or both ofthe disks E are taken off, and the longitudinal bars 1 are drawn outfrom the end, leaving the thread. supported upon the rods f, and theradial rods Z) 6', and leaving an open space inside i the threadsbetween them and the core A.

in this condition the bobbin and thread wound thereon are subjected tothe action of the reagent, and by reason of the way in which the threadis supported upon the bobbin, the reagent may be caused to flow from theinterior of the bobbin to the exterior by the rotation of the bobbin.

When treatment has been completed, the bobbin is placed in a windingmachine, and covered with a cap g, shown in dotted lines on Fig. d, theedge of which reaches approximately opposite the points 6 of the upperseries of radial rods. The lower set of radial roos, those having thestraight points Z), are drawn out of the core A, and the threads arethus supported by the upper ring of points 5. As these points 7) arecurved in a backward circumferential direction, there is no tendency forthe thread leaving the bobbin as it is drawn off above to catch upon thepoints.

Having now described my invention, 1

naaaeeo claim and desire to secure by lnited States Letters Patent:

1. A bobbin comprisi nal rods carried by said from the surface thereof,projecting: outward from the longitudinal rods.

2. A bobbin comprising a core, longitudinal rods carried by said coreand spaced from the surface thereof and from one another, andlongitudinal bars adapted to be removably disposed between said rods forcontact with a driving; drum.

3. A bobbin comprising a core, longitudinal rods carried by said coreand spaced from the surface thereof and from one another, and disksadapted to be remorably secured to said core, and longitudinal barsdisposed between said rods and supported by said disks.

4;. A bobbin comprising a core nd a series of radial rods projectingtherefrom, said rods having ends curved circumferentially in onedirection.

5. A bobbin comprising a core and a series of removable radial rodsadapted to support threads wound on the core against longitudinalmovement.

6. A bobbin comprising a core, a series of radial rods removablydisposed thereon, and a series of radial rods having circumferentiallycurved ends carried by said core.

" A bobbin comprising a core, longitua core, longitudicore and spacedand radial rods the core beyond 1. dinal rods carried by said core andspaced from the surface thereof and from one another, radial rodscarried by said core and projecting beyond said longitudinal rods, andremovable bars adapted to be placed between said longitudinal rods toform a frictional driving surface for Winding.

In testimony whereof I have signed my name to this specification.
